We use the library unconditionally, however not check it in
configure phase. Let's produce an error there and not at
compilation phase.
And while at it, drop -ldl from LDFLAGS too. I suspect it's
coming from the same source because in the gbm pkg-config file
private libs are to be linked with dl. But not only we are not a
gbm private library, we don't use dl*() anywhere.

Context array is declared as dec_ctx[VREND_MAX_CTX], virgl shouldn't accept id
== VREND_MAX_CTX.

It's unfortunate, but the i965 driver deliberately crash on such simple test
case. Fortunately, it seems fairly straightforward to avoid it in virgl.

The -I switch is meant for extending the list of paths searched
when looking for a header file. There's no justification in
having in linker flags.

There are places in the code where we use pthread_* functions,
but forgot to add corresponding bits onto the compiler command
line. Because of that the build fails:

If the current context is one of the subcontext to be destroyed,
vrend_destroy_sub_context() will fail after the last context is
destroyed.

Some american fuzzy lop tests managed to replace resources, however the
old values got leaked (I am not sure if this should be allowed)
In all cases, introduce a destroy callback to the hashtable, used when a
value is removed, replaced or the table is cleared. This simplifies a
bit resource management and help avoid potential errors by using simply
refcounts.

Resources are reference-counted, if another object holds a reference to
a resource, it should not free it. Change the resource hashtable destroy
callback to unref.
Currently, this doesn't happen, since the resource hashtable is kept
until the renderer is reset. However, in the next commit, the destroy
callback will be used if a resource is replaced in the hashtable, and we
want to keep the original resource. Furthermore, even if replace
shouldn't happen, it avoids confusion and future errors if use only
reference-counting mechanism.

Since the memcpy() is done over multiple of 4 bytes, over-allocate the
destination buffer to fit multiple of 4 shader length.

This is useful to do some quite accurate comparative
benchmarks/profiling, and to run fuzzers, such as american fuzzy lop.
